This nifty thermostat is actually built from just a few off the shelf components. A Dallas DS1820 1-wire temperature sensor provides and an Olimex ATMega development board. If you’re not so handy with the soldering side, you can pull this one off. The device can be programmed by the button cluster and will even output status via the serial port.
